[Bonetools] FW: identification of osseous raw material

[Sonia O'Connor]

Dear Miriam,
Thanks you for the extra photos.  Yes I think this is cetacean material, not only because of the size but also the open texture and the presence of what appears to be large osteon structures.

Dear Sonia,

Thank you very much for your response. I was rather inclined to think that this artifact is made of some kind of bone, just because of the possible suture you have pointed out. But... if it is bone, from what part of the skeleton? Because the thickness of the piece is 1.2 cm. In order to get such dense thick piece, the block of raw material should be larger than 1.2 cm...Has the skull of any animal this thickness? I am sorry, I have not enough experience to know it...

Could be from a cranium of a cetacean (without more analysis I know that could sounds adventurous)? I was thinking on that because other researchers have found pieces made in sperm-whale ivory in a Chalcolithic site in Portugal (http://tp.revistas.csic.es/index.php/tp/article/view/645/667).

I will not want to bother you but I send to you other photos, maybe they are not too good, but at this moment I have not others. Sorry.

Thanks for your help.
I wish you a good weekend.
Miriam
